Those who've seen the mainstream movie The Thirteenth Floor
will have a leg up on one of this feature's plot elements.
Fortunately, it's not a very important one, so everyone can
relax and watch Ava Vincent being targeted by the mysterious
Evan Stone, who's continually popping (literally) in and out
of her life, leaving messages daring Ava to do something
sexy.

And it's actually the Vincent/Stone/Dick Nasty finale that
scores highest among several reasonably hot scenes here.
Nasty has Ava crawl up a staircase to his dick, which she
expertly sucks before Evan enters and she has both cocks in
her mouth. Stone then has his pole up her ass as she rides
him, leaving some mish action before the oral climax.
